Muscadine Vines has numerous leaves with big yellow areas on them. We are in north Florida. We have never had issues in the past. Had some aphids earlier this year though.
This looks like one of the symptoms of Grapevine Fanleaf Virus. As it progresses, you will notice more deformation.
Complete removal of your grapes and replacing with an unrelated plant species will be necessary. This is not curable.

I have a male and female muscadine grape vines and they have been producing beautiful for 2 to 3 years. For some reason my female grape vine died. What do I for the male? I've tried to buy a female but cannot find no one with one. I appreciate any help you can give me. Thank you.
I find no mention of male varieties, only female and self-fertile varieties such as Triumph. Your male plant may actually be a self fertile variety, and if so, will produce fruit without the female. These articles will help:

Why is my Muscadine vine growing numerous roots along the branch well over a foot above the soil? The leaves are beginning to yellow and the grapes are shriveling! I have lost several large branches this year. No evidence of pests or leaf damage. Was 100% healthy last year. The roots are over a foot long! Nearby plants are Passion Fruit vines and Elderberry. The Muscadine vines are nearly 30 years old and have never had this problem before. Should I try to keep the roots wet or bury them?
Those are aerial roots and pose no harm. You do not need to cover or remove them. However, they can signal stress in the grapevine, such as winter injury. This article will help you check for other problems:

My wife has a trellis with orchids growing near it. Can they grow near each other.
As long as you plant them at least 4 to 5 feet from your existing bulbs, it should be ok. This will help you to care for it:

I received my 4 muscadime vines in a box all together in a bunch with their roots in a root ball. The root ball is wrapped and has tape on the outside. I was not planning on putting them in the ground until this latest cold snap has gone by. Should I leave them in the root ball until I plant or should I take them out and plant in a large pot until time to put in ground? If not, can I water the root ball?
They are best planted after the threat of frost has passed so you may have a month to go. In that case, you may want to plant them in separate containers and transplant them outside after all freezing weather is over. Here is more on their care:
